ENVIRONMENT

       DNSCACHEIP
              use IP address $DNSCACHEIP instead of 'nameserver' lines from /etc/resolv.conf

       LOCALDOMAIN
              use space separated names from $LOCALDOMAIN instead of 'search' line from /etc/resolv.conf

       DNSREWRITEFILE
              use $DNSREWRITEFILE file instead of /etc/dnsrewrite

NOTES

       dq rewrites IP address to *.in-addr.arpa or *.ip6.arpa for PTR queries e.g.:
         127.0.0.1 -> 1.0.0.127.in-addr.arpa
         ::1 -> 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
